Phytochemical and High-Performance Liquid Chromatography Analysis of Extract of Vernonia cinerea

The present study aims to screen and quantify hydroalcoholic extract for phytochemical content and HPLC profiles for standardization. HPLC was carried out using a RP-C18 analytical column with a mobile phase composed of acetonitrile: methanol (50:50 v/v) and was isocratically eluted at a flow rate of 1 mL min-1. A small sample volume of 20 μL was used for each sample run, being injected into the HPLC system. The chromatogram was monitored with UV detection at a wavelength of 256 nm. Phytochemical screening of the extract showed the presence of flavonoids, amino acids, carbohydrates and protiens in hydroalcoholic extract. Quantification of total flavonoids showed that hydroalcoholic extract of Vernonia cinerea had flavonoid content 0.547 mg/100mg equivalent to quercetin. The data presented here could be used for the standardization of hydroalcoholic extract of Vernonia cinerea, either for future studies or in herbal drug formulations.
